Look as I stated before, it is fine if you believe you hear no difference, if you believe that "DACS are a solved problem" and if you believe that I cannot hear a difference. (I certainly can and always have). Each of us is happy and neither of us has to denigrate the other. I have been listening to audio and have had systems since the late 60's. What I own now is what sounds good to me. I listened to well over 20 different dacs before I purchased my latest iteration and I purchased it because it sounded excellent to me - better than others I heard.
Not necessarily, Jim. One of the better sounding turntables I have heard is the Kuzma Stabi S for example.In my opinion this outperforms tts often costing 3x to 4x as much. So why did I mention this? To show that there are bargains around if you search for them and know what you are doing. However, once again, this is my opinion.
By the way, I have looked at most of the videos here, (though not all the way through in all cases as they bore me to tears). Also I am well aware of and confident in my own abilities, having been around for a while.
Hmm, my experience has taught me the exact opposite lesson. I was far more confident in my hearing abilities when I was in my 20s. Now that I'm in my 50s, I'm not nearly so confident. One, I'm certain my hearing acuity has worsened (I used to be able to hear 20kHz easily, now I can only hear to about 14kHz). Two, I've done blinded comparisons and learned just how easily my hearing can be fooled by casual (sighted, non-level-matched) listening comparisons.
